In the Philips line, the specific 60W model I mentioned earlier is their top of the line model. It has a very high 92 CRI (color rendering index) and is a warm white (2700K, I believe). They are not cheap, though (close to $50 a year ago but they are gradually getting cheaper). Philips does have similar but cheaper models that are not as high CRI, and not quite as energy efficient, but still very good.
I do not like "daylight" color lights for inside the house because I don't like really bright illumination in most situations and warm white look best to my eyes at lower light levels. So 2700K is just fine for me. My 75W-equivalent is also 2700K. Sounds like Izzy has maybe 5000K bulbs.
To me, the biggest recent improvent is that these LED bulbs actually send light out in all directions. Early LED bulbs tended to be highly directional and really were only suitable as floodlights or accent lights. I use one in a reading lamp next to my bed, sometimes pointed at my lap, sometimes pointed at the ceiling for ambient light. Excellent for reading, no flicker or hum. Very easy on the eyes. The other LED is the ceiling light in the bathroom.
LED is perfect for the bathroom since that light gets turned off and on more than any other light in the house and LED is basically immune to frequent cycling on and off. There is a slight but noticeable delay in turning on when you hit the switch, but it's not a big deal. The 75W packaging says that it is not suitable for enclosed fixtures, but I have it in a fairly voluminous frosted glass fixture. I don't think it throws off enough heat to shorten its lifespan from overheating inside this fixture, but I'm prepared to see what happens. The 60W only gets warms to the touch while the 75W bulb does have small metal cooling fins built into the "stem" of the bulb and they get fairly hot.
Cree brand also has a new line of LED bulbs that I would like to try out, too, but haven't seen them in any stores yet. I believe they're close to the $10-15 range, so manufacturers are steadily reducing the price. Cree is a major LED manufacturer and their LED emitters are in most high powered LED flashlights that people talk about but I think this is their first foray into a consumer lightbulb.
If you want very bright light, though, LED is still not quite there. It might be more subjective than an absolute difference, but I don't think a "75W equivalent" LED looks as bright as an incandescent bulb to the eye. Then again, it only uses 13W of power.
